at the start:
special = re.compile('<![^<>]*>')
then later:
match = special.match(rawdata, i)
if match:
    if self.literal:
        self.handle_data(rawdata[i])
        i = i+1
        continue
    i = match.end(0)
    continue

so if you want to handle <!DOCTYPE> it needs to be in a data handler.
